DUMPING APPARATUS FOR COAL-CARS.

Specification of Letters Patent.

Application filed November 16, 1910.

Patented Sept. 5, 1911.

Serial No. 592,637.

To all whom it may concern.

Be it known that T, HENDERSON H. BEN- NETT, a citizen of the UnitedStates, residing at Morley, in the county of Campbell and State ofTennessee, have invented certain new and useful Improvements in DumpingApparatus for Coal-Cars; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in dumpingapparatus for coal cars or the like.

The object of this invention is the pro vision of a device of thischaracter, whereby the car will be impelled by its own weight to adesired dumping point and automatically dump, and after which bereturned automatically to the starting point. V

A further object of this invention is the provision of a device of thischaracter which will be comparatively simple and inexpensive tomanufacture, reliable and eflicient in use, and readily operated.

With the above and other objects in view this invention resides in thenovel features of construction, formations, combinations andarrangements of parts to be hereinafter more particularly described,claimed and illustrated in the accompanying drawing, in which- Figure 1is a plan view of my dumping mechanism; Fig. 2 is a longitudinalsectional'view taken on the line a-a of Fig. 1; Fig. 3 is an end view ofFig. 1, with parts broken away; and Fig. 4 is a side elevation of myinvention.

Referring to the drawing by characters of reference, the letter Arepresents a point of excavation, or any other desired spot from whichcoal or the like is to be moved, and B the dumping point, or place towhich the said coal or the like is to be conveyed and deposited.

My improved device is mounted upon a suitable trestle work 1, andcomprises a main track 2, which slopes gradually downward from the pointof excavation A to the dumping point B, and a side track 3, which slopesdownward from the dumping point B back to the point of excavation A.

A hinged platform 4 having a vertical swinging movement, is mounted insuitable bearings 5, adjacent the previously mentioned dumping point B,and has mounted thereon the terminals or switch points of the main track2, which are connected by a suitable bar 6, and normally pressed bymeans of a spring 7 in a direction so as to admit the dump car 7 to betransferred to the side track 3 upon its return. A frame 8 is secured tothe lower face of the swinging platform 4, and is provided withdepending guides 9, adapted to receive the swinging extremities of asubstantially U-shaped returning member 10, provided upon its upperinwardly extending arms with suitable guides an, adapted to engage ashaft 1), and permit of the outwardly and inwardly sliding movement ofthe said member 10, and adapted to slide longitudinally of the saidplatform 4, the same being normally held in its innermost positionthrough the medium of weights 11, mounted in suitable guides 12 carriedby the trestle work and connected to the said returning member by cables13, passing over pulleys 14, mounted on a transverse bar or rod 15,connecting the opposite sides of the said frame 8. The intermediateportion of the U-shaped member is curved upwardly and provided with avertical extension 16, adapted to engage the stop 17, projectingforwardly from the front end of the dump car 7.

The main track 2 is provided at its juncture with the siding with asingle switch point 18, which is normally held out of engagement withthe alining track, but which will be normally swung into engagement bythe weight of the car in passing over the same, while the terminals ofthe said track adjacent the dumping point are curved upwardly to providestops, which limit the movement of the car in the direction of the saiddumping point.

A forwardly curved bar 19 is secured to the forward end of the platform4, passes through a guide 20, located in one of the cross beams of thetrestle work, and has formed upon one edge therof a series of teeth 21,adapted to engage the upper end of a locking pawl 22, mounted upon aswing ing bar 23, provided with a weight 24, adapted to normally forcethe said pawl into engagement with the said teeth. A depending trip arm25 is formed integrally upon the swinging bar, and connected through themedium of a cable 26 to an upwardly extending trip arm 27, pivoted atits intermediate portion to the trestle work at a place adjacent theexcavation point A.

The front of the car 7 is provided with a hinged closure 28, adapted toswing upward as the car is tilted and permit the contents thereof to bedumped.

The operation of the device is as follows: After the car has been loadedit will be impelled by its own weight, after the brakes have beenreleased, down the main track to the swinging platform 4, obviouslyengaging the vertical extension 16 formed upon the U-shaped member,moving the same to its outward position and permitting the wheels tomove in advance ofthe switch points and allowing them to return to aposition which will permit the car to ride upon the siding. A lever 28is secured to the frame work for manually tipping the platform. Thecurved bar carried by the forward end of the platform will obviously beraised, while the teeth on its rear edge will be engaged by the pawl,retaining the platform in its tilted position. The next car, upondescending to the dumping point will manifestly release the pawl throughthe medium of the previously mentioned trip arms 25 and 27, allowing theplatform to return to its horizontal or normal position, and theU-shaped member to slide inwardly to its normal position by means of theweights 11, which operation will start the empty car on to the siding inthe direction of the starting point. As the second mentioned car reachesthe platform 4, the said platform will be tilted in the previouslydescribed manner, and upon the descent of the next car the operationwill be continued as before.

From the foregoing disclosure it will be manifest that a dumpingmechanism is provided for which will fulfil all the necessaryrequirements of such a device.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

L'The combination with a main track and a siding, of a platform mountedthereon, the said platform adapted to be tilted by the weight of a car,a curved bar mounted on said platform and adapted to engage a pawlmounted therebelow and retain the platform in its tilted position, and asliding member mounted upon the tilted platform and adapted to returnthe car over the siding upon the release of the platform by an advancingcar in passing over the main track.

2. The combination in a device of the class described, of a main trackand a siding, a tilting platform hinged at the juncture of the maintrack and the siding, a longitudinally slidable member mounted upon thetilting platform, means for tilting the platform and retaining the samein its tilted position, and means for releasing the platform andsimultaneously sliding the longitudinally movable member upon therelease thereof, for the purpose of returning a car over the siding.

3. The combination with a main track and a siding, of a tilting platformhinged at the juncture of the said main track and siding, the saidplatform adapted to be tilted by the advance of a car upon saidplatform, a slidable member mounted upon the platform, said memberadapted to slide rearwardly upon the approach of a car, and to allow thewheels of the same to move to the rear of a switch point carried by saidplatform, whereby the car may be returned over the siding upon therelease of the platform by the action of the slidable member thereon,weights secured to the sliding member for returning the same upon therelease of the platform, a toothed bar secured to the platform, a pawlmounted below the said platform and adapted to engage the tootheddepending bar and retain the said platform in its raised position, and atrip arm mounted upon the main track and connected through the medium ofa cable to the pawl, whereby the said platform may be released by thecontact of a car against the said arm, and the sliding member swunginwardly for the purpose of returning the car which is upon the tiltingplatform over the siding, substantially as and for the purposeshereinbefore described.

In testimony whereof I aflix my signature in presence of two witnesses.
